It wasn't silly at all, though Draco knew he'd never make her see that. If she'd made up her mind to disagree with him, disobey him, she'd do it, and he knew somewhere bone deep that it wasn't any good at all to argue the point. Instead he turned her hand over in his, studied it absently for a moment. "Just don't do anything public, alright? I can't hide the both of us." And how much he'd have to do depending on Snape, and nothing at all on himself, which meant he'd likely be too damn busy to always keep an eye on her.
